Hendo Hoverboard??

Um, what?

I'd like to believe but, this could so easily be a scam, like the "E-Cat" BS that iS STILL going on. Ugh.

I find it hard to believe that a new motive technology like this could be developed without the Pentagon's mitts all over it.

Seems like it's just a magnetised board floating over a metal surface. If so it's an impressive bit of tech, but it's nothing especially innovative.

That's what it seemed to me as well, though I really can't know enough about it to gainsay the inventors. If it is what it seems, then the real world applicabability is just about nil.

Having something floating above something because of magnetism is old tech.

Actually, I could be wrong but I'd say the most impressive thing about it is that they managed to have a battery with enough juice to run the electromagnets in the thing and support a grown person's weight. I'd love to know what voltage/current the thing runs on, and how long a battery lasts.

Agreed.

A critique of the board.

Yes, it's magnets - apparently spinning magnets in the board itself. Battery life is "a couple of minutes".

And despite the hype that "this is a prototype", leading towards a hoverboard you can use anywhere, or "levitate buildings" - in reality the board's batteries last "a couple of minutes", it weighs almost 80 kg, there is no prospect whatsoever that it will ever be able to be used outside of specially constructed metal surfaces, and levitating buildings with this technology is an absurd notion.

What the hell would you do with a levitating building anyway, besides not be able to get in?

Well believe it or not the people hawking this talk about it as as solution to rising sea levels and flooding.

You get in on your hoverboard, of course!

They don't work on water. Unless you got power.

I believe it... if the people saying it are stupid. Presumably, the platform works (if it would ever wrk for something building-sized) with a finite maximum altitude over the substrate magnets. Flooding and rising sea levels, however, have a stubborn tendency to ignore maximum levels like that. So, the levitating-building idea can only ever be a solution to rising sea levels and flooding... that will not rise any further than we ask them to.

Couple of weeks ago I was watching a show about a guy who built a floating house. It was a huge concrete box dug into the ground that the house sat in, with metal guide rails standing vertically that the house was attached to so it could only move straight up and down. When it flooded, the box filled with water and the house floated up the rails. As the water receded the house slid back down again.

No power required, no magnets, no metal surfaces... yeah, I don't think we're really in dire need of magnetic levitation as a flood defence.

Interesting piece of enigineering. I wonder how they designed it so there would be enough water to make the house buoyant.

That's the principle :
